Prof. Eryk Wdowiak

In class yesterday, Sammy snapped some great photos of the derivation of the OLS coefficient estimates. I have posted them here, so that they will serve as a quick review.

In class next Sunday, we will finish our discussion of Homework #1c. To assist you in solving the problems, I have posted a wxMaxima notebook with an explanation of MLE.

See you in class on Sunday.
